3 Claims. (Cl. 242-43) This invention relates to a wrapping machine receives a tire to be wrapped in the usual manof the type adapted to apply a protective wrapner and has secured thereto the necessary equipping to tire casings and other similar annular ment for'wrapping with paper IE or the like.

More particularly the invention relates The tire is supported in an upright position on I to improvements in the guiding and positioning drums l6 and ll which are driven from shaft means for tire casings being wrapped in the l2 through connections indicated as a Whole type of machine described and claimed in my by the numeral l8. These drums serve to rotate Patent No. 1,635,288, granted July 12, 1927. the tire while it is being wrapped.

In said patent the guiding and positioning Drum H is mounted on a shaft l9 which is means which comprise a pair of upwardly flarrotatably supported on suitable arms 20 that ing rollers are entirely satisfactory when tires are rotatably supported intermediate their ends having relatively smooth treads are being on shafts 2| which in turn are mounted on wrapped, but when tires of the type now bebrackets 22 extending from the base II.

Thus, even rotation of the tire is assured at all times and the sets of rollers are not kept in a state of constant agitation as is the case with a single roller.

It is believed to be apparent that my invention has not only provided a means to permit satisfactory wrapping of heavy-lugged tires, but the rollers themselves and the movable parts associated therewith will have a much longer life than single rollers since they are not subjected to the constant jumping movement of the single rollers. It will also be apparent that the number of rollers provided in each set may be varied to suit the conditions under which the machine is operating, and that the invention may be utilized with other types of wrapping machines.

While I have shown and described the preferred form of my invention, it is to be understood that the invention is not so limited, and various modifications may be made within the spirit of the invention and within the scope of the subjoined claims.

What is claimed is:

1. In a wrapping machine for annular articles, a pair of spaced drums for supporting the articles in an upright position, and means pivotally supported adjacent one of said drums to position and guide said articles, said means comprisa pair of sets of rollers, the rollers of one set being arranged in alignment with each other in a plane which lies at an angle to the vertical,

and the rollers of the other set being arranged in alignment with each other in a plane lying opposite to the first mentioned plane, the arrangement being such that the respective sets of rollers are in upwardly and outwardly flaring positions.

2. In a wrapping machine for annular articles, the combination with a drum for supporting the articles in an upright position of a pair of sets of rollers pivotally supported adjacent said drum to assist the latter in positioning and guiding said articles, the rollers of one set being arranged in alignment with each other in a plane which lies at an angle to the vertical, and the rollers of the other set being arranged in alignment with each other in a plane lying opposite to the first mentioned plane, the arrangement being such that the respective sets of rollers are in upwardly and outwardly flaring positions.

3. In a wrapping machine for annular articles, the combination with a drum for supporting the articles in an upright position of a pair of parallel arms pivotally mounted, one at each end of said drum, a plate connected between said arms, a pair of spaced pins extending upwardly from said plate, a bracket mounted on each pin, means preventing turning of said brackets on said pins, and a set of rollers carried by each bracket, said sets of rollers being arranged in upwardly and outwardly flaring positions with respect to each other.
